Add a definition To correct for this orbital perturbation, regular orbital stationkeeping manoeuvres are necessary, amounting to adelta-vof approximately 50 m/s per year. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Over a time "t" the change in speed of the spacecraft is ("a" - "g") "t", whereas thedelta-vexpended is "at". From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. A rocket stage, while carrying a given load, is capable of giving a particulardelta-v. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Currently, 2-4 stages are needed to achieve the requireddelta-v. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. For low exhaust velocity with respect to the missiondelta-v, enormous amounts of reaction mass is needed. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The velocity of the vehicle needs substantial burns at the intersection of the two orbital planes and thedelta-vis usually extremely high. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. In this case a gravity turn is not the optimal entry trajectory but it does allow for approximation of the truedelta-vrequired. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. In astrodynamics, this energy expenditure is defined by the net change in the spacecraft's velocity, ordelta-v. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. It is also notable for having a lowdelta-vrequirement for rendezvous. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. It is typical to combine the effects of these and other effects into an effective missiondelta-v. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Thedelta-vto make the necessary plane change is typically extremely high. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The actual acceleration of the craft is "a" - "g" and it is usingdelta-vat a rate of "a" per unit time. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The early business model for these services is primarily in near-geosynchronous orbit, although largedelta-vorbital maneuvering services are also envisioned. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. To reach low earth orbit of the space station of 300 km, thedelta-vis over six times higher about 9.4 km/s. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. To reach orbit, the rocket must impart to the payload adelta-vof about 9.310 km/s. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Orbital speed is slower for higher orbits, but attaining them requires higherdelta-v. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Thus, the effectivedelta-vrequirement for these vehicles are reduced. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Also, the equation strictly applies only to a theoretical impulsive maneuver, in which the propellant is discharged anddelta-vapplied instantaneously. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. Thedelta-vneeded to achieve low earth orbit starts around 9.4 km/s. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license. The correction of this effect requires orbit control manoeuvres with a maximumdelta-vof about 2 m/s per year, depending on the desired longitude.
